T-55T1 variant of the T-55T support chassis (based off of the T-54/55 tank hull). T-55T's lack a crane, while the T1 has a small crane on the rear-right side of the hull. The bigger T-55T2 has a much larger crane mounted on the left-middle of the hull which overhangs the back of the vehicle by several feet. All variants have a small open-topped box at the rear of the hull.
